Need to describe why each method can throw.
e.g. add, etc. throw if called on or passed a LengthValue that isn't a SimpleLength or CalcLength.
parse throws if the DOMString isn't a valid representation of a length.
I don't think fromValue, fromDictionary can throw.
| and returns the result as a new {{LengthValue}}. This will construct | ||
| a {{SimpleLength}} if the object is a {{SimpleLength}}, or a {{CalcLength}} | ||
| if the object is a {{CalcLength}}. | ||
| if the object is a {{CalcLength}}. The function can throw a DivideByZerError if value given is 0. |
