fracture 0.2.0

Breaking changes

• The second argument to fracture() and frac_mat() is now ..., which must be empty. As a result, all arguments besides x must now be named. (#5)
• fracture() and frac_mat() now default to a denominator of 1 when x equals 0 or 1. Previously, these would default to a denominator of max_denom. max_denom is still used as the denominator when x is 0 or 1 ± ε. (#6)

New features

• fracture() and frac_mat() gain the argument denom, which allows the user to set an explicit denominator used by all fractions. (#5)

Miscellaneous

• The print() method for fractures now puts quotes around mixed fractions to increase legibility. (#7)
• Updated testthat to 3rd edition. (#5)
