Make error messages from the lexing and parsing stages be a bit more helpful. If
provided with the input and a position, the error will display the error
position, and the nearby input with the error position underlined (yay combining
marks). Also, standardize the errors a bit (remove doubled "Error:" strings)
Test plan:
- Make sure the errors look totally sweet (before: {F15602}, after: {F15603})
- Trigger every error (that can be triggered) in Parser, Lexer, and buildTree
using the inputs:
`a^`
`a_`
`a^x^x`
`a_x_x`
`\color f`
`\blue `
`\Huge`
`\llap`
`\text`
`\dfrac`
`\dfrac{x}`
`\d`
`\blue{`
`\color{#f`
`{\Huge{x}}`
- See that the tests still work
