support ascii math

[HeinrichAD]

For documentation purpose:

Many years pasted and somewhere in between the support was added.

Example 1

Source code taken from here: https://plantuml.com/ascii-math

@startuml
:<math>int_0^1f(x)dx</math>;
:<math>x^2+y_1+z_12^34</math>;
note right
Try also
<math>d/dxf(x)=lim_(h->0)(f(x+h)-f(x))/h</math>
<math>P(y|bb"x") or f(bb"x")+epsilon</math>
end note
@enduml

renders as:

Example 2

@startmath
sum_(i=1)^n i^3=((n(n+1))/2)^2
@endmath
