titleize

Small wrapper around the titlecase library to convert text to title case.
It follows the rules defined by John Gruber.
For more details, refer to the library.

titlecase applies a show rule, that by default transforms every string of at least four characters.
This limit can be changed with the limit parameter.
Especially with equations, the results can be a bit unpredictable, so proceed with care.

= This is a test, even with math $a = b + c$

In math, text can appear in various places:

$
  a_"for example in a subscript" &= "or in a longer text" \
  f(x) &= sin(x)
