A small graphical calculator project.

Tomorrow Graphing Calculator

A small learning project to develop a simple, 2D, cross-platform graphing calculator. You give it some functions, it gives you a plot of that function - that's all that we're going for at the moment.

We're all new devs, and we welcome anyone who's interested in contributing - say hi, ask questions, help out on some issues - we try not to bite.

Function Parsing

The current system for parsing functions seems slightly hack-y. Instead of dealing with strings all the way through, we should parse each item in our input string into a 'symbol', so that our string turns into an array of symbols.
A symbol would be a generic type with minimal data associated with it. Something like:

Private source character
A getData method - just so we can get the raw representation of what this symbol is, e.g. '*' or "sin"
A handle method - if the priority level (which controls the order of operations) is high enough, then resolve this operation. For example, if the symbol was a multiplication, the handle function would check if we're at the point to do multiplication, then carry it out. Not all symbols need a handle method e.g. constant numbers don't need to be 'handled', they are acted on by other symbols.

These symbols would then be organized in a list.
In this way, binary operators (+, -, *, /) could easily be implemented, as they'd basically have to do:
newSymbol = symbols[n-1] + symbols[n+1]

No README for test-branch

Seriously disappointing.

Add precompiled headers

Compilation takes way too long especially if multiple files dealing with the CImg library have to be recompiled.

Add README for master branch so that people get what the project is about
