Error while parsing latex

[magicaltoast]

/ a\cdot3 is parsed as variable not as multiplication.

buildFunction method returns a function that looks like this

anonymous(acdot3) {
 return acdot3;
}

If you input
/ 3\cdot2 it generates something like this

anonymous(cdot2) {
 return 3*cdot2;
}

Also, I am unable to parse any kind of sum. Throws ```Cannot read property 'column' of undefined: undefined: undefined: undefined`` exception.

Example:
/ \sum_{n=1}^{10}n

The multiplication error can be fixed with following regex replace(/\\cdot(\S)/g, '\\cdot $1').

Also weird behavior after an assignment in another equation
Every equation is compiled to return 20

const nerdamer = require("nerdamer");

nerdamer.convertFromLaTeX("x=20");

const weird = [
  "x+20",
  "x*20",
  "x-20",
  "x^{20}",
  "\\frac{x}{2}",
]

weird.forEach(eq=>console.log(nerdamer.convertFromLaTeX(eq).buildFunction().toString()))

The trigonometric function, log works fine. clearVars fix this issue but it's still strange behavior.
