Use less dictionary object and create more classes

[rjodon]

I can see everywhere this object components = {'x': x, 'y': y, 'z': z, 'xx': xx, 'yy': yy, 'zz': zz}
I would rather create a component like this:

class Components:
    def __init__(x=0. y=0, z=0, xx=0, yy=0, zz=0):
        self.x = x
        self.y = y 
        etc... 

after it's much easier to access the individual components self.components.x is much lighter than self.components['x'] also we can add plenty of helpers inside the components class

indeed, in the case of compas_fea the bottleneck will always be the actual analysis, so we should design the entire infrastructure for convenience and not performance...

Agree. most of those dictionary are obsolete anyways. I will remove the unnecessary ones and then we can refactor the remaining.
