Description
template<typename T>
class Sawyer::CommandLine::RealNumberParser< T >
Parses a real number and converts it to numeric type T.
Matches a real number in the mathematical sense in C++ floating-point representation, and attempts to convert it to the type T. If the real number cannot be converted to type T then an std::range_error is thrown, which is most likely caught by higher layers of the library and converted to an std::runtime_error with additional information about the failure. The syntax is that which is recognized by the strtod function, plus trailing white space.

Allocating constructor.
Returns a pointer to a new RealNumberParser object. Uses will most likely want to use the realNumberParser factory instead, which requires less typing.
