tatoo 1.1.1

removed purrr and rlang dependencies
table_id is no longer pasted to the title when creating excel output. If you require the old behaviour set .print_table_id = TRUE
small updates to some tests for compat with data.table 1.12.2 (https://github.com/statistikat/tatoo/pull/5)

tatoo 1.1.0

Add Named Regions for table parts Excel Sheets to make formatting easier
Added walk_regions() and map_regions() to mainuplate cells in named regions within a Workbook (e.g. apply formatting to them)

Bugfix release
Fixed faulty example code for open_file()
Removed default arguments of save_*() functions (they wrote to the users home directory by default)

Convert Tatoo_table objects to Latex code or save them directly to .pdf with as_latex() and save_pdf() (experimental).
Added open_file() utility to open files with external programs.
Added view_pdf() and view_xlsx() for directly viewing tables in a .pdf viewer or spreadsheet program
save_xlsx() now returns the path to the saved workbook, raher than the workbook object
Various small fixes related to print() methods

Minor tweaks for compatibility with purrr 0.2.2
as_Composite_table.data.table() converts data.tables to Composite tables, based on separators in the column names (e.g fruit.apple, fruit.banana)
Improved README / vignette / documentation
Changed how as.data.table.Composite_table() constructs column names. The new format is colname.multiname instead of multiname.colname. This is to emulate the behaviour of base::merge()
flip_names() can flip names and multinames of a composite table (at the cost of reordering the columns)
