Detailed Description

template<class T>
class Heed::EqualStepCoorMesh< T >

Mesh with equal steps. Determined by the number of "bins", minimum and maximum. The object of this class keeps all ingredients in it. It can be therefore copied and deleted freely. T is the type of returned value. T cannot be const. At construction q has meaning of number of intervals.
