Switched to cpp11 from Rcpp.
Relicensed as MIT (#51).
obj_size() and sxp() now support non-nil terminated pairlists.
obj_size() now displays large objects with KB, MB, etc (#57, #60),
and no longer returns NA for objects larger than 2^31 bytes (#45).
obj_sizes() now computes relative sizes correctly (without meaningless
floating point differences).
ref() lists all contents of environments even those with names beginning
with . (@krlmlr, #53).
New, experimental tree() function as alternative to str() (#56).
Fix PROTECT error.
Remove UTF-8 characters from comments
ref() now handles custom classes properly (@yutannihilation, #36)
sxp() is a new tool for displaying the underlying C representation
of an object (#38).
obj_size() now special cases the ALTREP "deferred string vectors" which
previously crashed due to the way in which they abuse the pairlist type
(#35).
