Orienting the support

Hi Graig,

Hope you are doing well and hope you remember me. I have released the standardsolver beam analysis and it is getting some good reviews. It is not very popular yet but I am spreading the message. Got some good reviews in Reddit.

I am now working on building a similar calculation for 2D frame analysis.

**I have a feature request if it is possible.**

For nodal supports, they can be only aligned in global X, Y. Is there a way to specify an angle to them with respect to the global axis, For example, if you want to apply only lateral restrain to an inclined member and allow the member to move axially free, At present, it seems it is not possible from reading the wiki.

Start by reviewing the wiki's description of nodal supports and locating the existing support implementation for global X and Y restraints. Clarify the intended angle representation and API before planning the change; done should allow an inclined member's lateral restraint while leaving its axial movement free, with the behavior documented and tested.
