Templating FieldUtils::Interpolator

Issue/feature addressed

Templating of the FieldUtils::Interpolator class

Proposed solution

The idea is to template the FieldUtils::Interpolator class. This will be useful for future code development. The original class was designed for std::vector<MultiRegions::ExpListSharedPtr> variable type. Templating will also allow Array<OneD, MultiRegions::ExpListSharedPtr> variable type.
