Detailed Description
template<typename F>
class hp1D::RefineOrRaise< F >
Refines element or raises its polynomial degree.
The decision is based on a log linear regression to find out if the Legendre coefficients of the solution decrease exponentially.
The parameter theta is used to control this decision. If 
is less than theta, the element's polynomial degree is raised, otherwise it is refined. m is the slope of the fitted line in the regression.
