Namespaces
namespace	utility
	unresizable vector whose size is known at compile time, which may be allocated on the stack, and which indexes from 1.
Functions
void	utility::ReadFromFileOrDie (const std::string &filename, std::string *contents)
	Reads the contents of <filename> into <contents>, preserving newline characters. Aborts if an error is encoutered.
std::vector< std::string >	utility::split (const std::string &s)
	split given std::string using ' ' symbol.
std::string	utility::join (utility::vector1< std::string > const &s, std::string const &connector)
	combine strings with anything
std::string	utility::join (std::vector< std::string > const &s, std::string const &connector)
	combine strings with anything
std::string	utility::join (std::string const &string_w_spaces, std::string const &connector)
	join space separations in a string with a connector such as '_'
std::list< std::string >	utility::split_to_list (const std::string &s)
std::vector< std::string >	utility::string_split (std::string const &in, char splitchar)
float	utility::string2float (std::string st)
int	utility::string2int (std::string st)
void	utility::string2uint (const std::string &x, unsigned int *y)
bool	utility::startswith (std::string const &haystack, std::string const &needle)
	True iff haystack starts with needle.
bool	utility::endswith (std::string const &haystack, std::string const &needle)
	True iff haystack ends with needle.
void	utility::slurp (std::istream &in, std::string &out)
void	utility::trim (std::string &s, const std::string &drop)
std::string	utility::trim (std::string const &s, std::string const &drop=" ")
	create a new string that drops all the unwanted substrings of the original string.
bool	utility::trimmed_compare (std::string const &s1, std::string const &s2)
void	utility::add_spaces_left_align (std::string &st, std::size_t const newlen)
	adds spaces to a left aligned string until a given length is reached
void	utility::add_spaces_right_align (std::string &st, std::size_t const newlen)
	adds spaces to a right aligned string until a given length is reached
bool	utility::is_string_numeric (std::string const &input)
std::string	utility::file_contents (std::string const &file_name)
	Read the entire contents of a file into a string. All end-of-line characters are replaced by "\n". Throws a utility::excn::EXCN_msg_exception if the file cannot be opened.
std::string	utility::file_basename (const std::string &full_path)
std::string	utility::filename (const std::string &path)
std::string	utility::pathname (const std::string &path)
std::string	utility::replace_environment_variables (std::string input)
	find all environment variables with the form ${VARIABLE} and replace with the contents of that environment variable. if the environment variable does not exist, return string::npos
bool	utility::same_ignoring_spaces (std::string const &s1, std::string const &s2)
	Compares two strings, ignoring spaces. Useful for comparing atom name strings which have pdb-alignment built into them. Slightly dangerous if you consider the fact that atom names in the PDB are different for different indentation rules: ' CA ' is c-alpha. 'CA ' is calcium.
void	utility::replace_in (std::string &s, const char from, const char *to)
template<class T >
std::string	utility::to_string (const T &t)
template<class T >
T const	utility::from_string (std::string const &s, T)
