This class is the abstraction of a one-dimensional multi-elemental expansions which is merely a collection of local expansions.
This multi-elemental expansion, which does not exhibit any coupling between the expansion on the separate elements, can be formulated as,
where is the number of elements and is the local elemental number of expansion modes.
Instances of this class may be optionally constructed which use generalised segment expansions (LocalRegions::GenSegExp), rather than the standard segment expansions (LocalRegions::SegExp). LocalRegions::GenSegExp provides additional spatial data including segment normals and is enabled using the UseGenSegExp flag.
This class inherits all its variables and member functions from the base class MultiRegions::ExpList.

This constructor sets up a list of local expansions based on an input graph1D.
Given a mesh graph1D, containing information about the domain and the spectral/hp element expansion, this constructor fills the list of local expansions {m_exp} with the proper expansions, calculates the total number of quadrature points and local expansion coefficients and allocates memory for the arrays m_coeffs and m_phys.
For each element its corresponding LibUtilities::BasisKey is retrieved and this is used to construct either a standard segment (LocalRegions::SegExp) or a generalised segment (LocalRegions::GenSegExp) which is stored in the list m_exp. Finally, ExpList::SetCoeffPhys is called to initialise the data storage areas and set up the offset arrays.
