Implement single shape function calculation per element type. about femur HOT 2 CLOSED

A first guess of what could be done is using a class variable to keep track of whether or not the shape function has been calculated in the first place.

I will implement this soon enough.

Here is a quick snippet of what I am talking about:

class A(self):
    Ne_ref = None
    __init__(self):
        self.Ne_ref = None

    def get_Ne_ref(self):
        if A.Ne_ref is None:
            <Get Shape Function Code>
            A.Ne_ref = <result>
            self.Ne_ref = A.Ne_ref
        else:
            self.Ne_ref = A.Ne_ref

This change was made to all pre-defined element2D sub-classes, because if more than one type of element is evaluated in the code, each type of elements' shape functions need to be independent (different from other element type.)
