Brief description of what is fixed or changed

This PR implements remove_load method to remove previously applied loads on the beam object.
This is little different from adding a negative load to make net equal to zero and would work only if that particular load exists on beam. example:

>>> b.apply_load(4, 2, -1)
>>> b.remove_load(1, 2, -1)  # will give ValueError as no such load was present on beam
>>> b.remove_load(4, 2, -1)  # will remove the load

I also implemented applied_loads method which keeps a track of all load applied on beam.
It is different from b.load as it treat each load as a separate entity. load property would sum up all the loads at a particular point but applied_loads will still show them as separate loads. For example

>>> b.apply_load(4, 2, -1)
>>> b.apply_load(2, 2, -1)
>>> b.load
6*SingularityFunction(x, 2, -1)
>>> b.applied_loads
[(4, 2, -1, None), (2, 2, -1, None)]
