v0.1

Very basic early alpha. So far all it can do is take a simple math expression input and display the answer in a gui. I also made a LaTeX input box for future algebra calculations. Planned features include algebra and graphing with line summaries (all intercepts and points of interest in a readable format rather than having to search through the graph). It even has error handling! https://github.com/Coosanta17/Java-Calculator/commits/v0.1
