aliases: Aliases
In smbache/nestpas: Pipe Friendly Aliases

nestpas provides a series of aliases which can be more pleasant to use when composing chains using magrittr's %>% operator.

Currently implemented aliases are

`add`	`+`
`and`	`&`
`divide_by`	`/`
`divide_by_int`	`%/%`
`equals`	`==`
`extract`	`[`
`extract2`	`[[`
`inset`	`[<-`
`inset2`	`[[<-`
`is_in`	`%in%`
`is_greater_than`	`>`
`is_less_than`	`<`
`is_weakly_greater_than`	`>=`
`is_weakly_less_than`	`<=`
`mod`	`%%`
`multiply_by`	`*`
`multiply_by_matrix`	`%*%`
`not` (`n'est pas`)	`!`
`or`	`\|`
`raise_to_power`	`^`
`set_attr`	`attr<-`
`set_attributes`	`attributes<-`
`set_colnames`	`colnames<-`
`set_comment`	`comment<-`
`set_class`	`class<-`
`set_dim`	`dim<-`
`set_names`	`names<-`
`set_rownames`	`rownames<-`
`subtract`	`-`
`use_series`	`$`
