Detailed Description

template<typename Data_T>
class Gw::Measure< Data_T >

A general measure with an associated error.

A measure is obtained experimentally. It is then a number associated with an error.
This class inherits from InfoData since a measure can be qualify as defined in InfoData.

Use this template class with Double_t or Float_t depending on the precision you need. It requires only a definition of the = operator for any other utilisation (vector of points and associated errors ... etc)
