Encode symmetric condition onto the governing equation

[Xupeng-Sui]

Hello @lululxvi and everyone interested in,

DEEPXDE is quite a powetful and amazing package to solve problems in a efficient way!

However, I have no idea on how to apply symmetric condition onto the outputs from solving governing equations.

For example, if we have two different outputs within a governing equation system, let's say y1, y2, how should I encode the condition 'y1(-x) = y2(x)' when defining this physcial system?

Best appreciation for you all!
