Implement SWIG wrapper to get_element returning a python element object

This is an implementation of a SWIG wrapped python module get_element
that provides a method:

  e = get_element(dim, vertices, quadrature_degree, polynomial_degree)

where e is a python element object, equivalent to the struct returned by
the get_element function in C, with the following members:

  dim - integer
  ngi - integer
  polynomial_degree - integer
  quadrature_degree - integer
  quadrature_family - integer
  vertices - integer

  get_dn - method returning dn as NumPy array
  get_l - method returning l as NumPy array
  get_n - method returning n as NumPy array
  get_weight - method returning weight as NumPy array

do not wrap struct element as python class

Remove argout typemap and wrap only function with the changed signature

This hides the element struct from the python caller. Now only this
method is available from python:

  weight, l, n, dn = get_element(dim, vertices, quadrature_degree, polynomial_degree)

Add typemaps to SWIG interface file to convert double* to NumPy array

Instead of only filling the element struct, a tuple of NumPy arrays is
returned. This changes the signature of the python function to:

  weight, l, n, dn = get_element(dim, vertices, quadrature_degree, polynomial_degree, element)

To avoid the necessity of creating an element object and passing it in
in the first place, SWIG adds another function that internally creates
an element object and hides it entirely from the caller, again
returning a tuple of NumPy arrays:

  weight, l, n, dn = get_element(dim, vertices, quadrature_degree, polynomial_degree)

Add SWIG wrapper to expose get_element as a python module

The python interface is generated with SWIG and all the module get_element
depends on are built into a shared object which is then loaded by the python
module.

Currently the actual data is exposed to python as double* and is hence not
useable. It needs to be wrapped as a NumPy array.

Add F90 subroutine to extract quadrature and shape information from element

Subroutine get_element will be exposed to python via a wrapper in C and
hence needs to be C interoperable. It takes a C interoperable derived
type c_element_type as last parameter with intent inout containing all
the requested information about an element given its dimension,
vertices, polynomial degree and quadrature degree.
