Arrange a data frame by the possibly the `group_vars()`

(optional, but defaults to off) and `arrangeTerms`

. Accepts arbitrary text as
arrangeTerms to allow forms such as "desc(gear)". Intent is to arrange only by
sets of variables with desc() notations reversals, not by arbitrary expressions over variables.
To help enforce this parsing is performed in an empty environment (so expressions
such as "gear + carb" deliberately error-out).

arrange_se(.data, arrangeTerms, ..., .by_group = FALSE, strict = TRUE)

`.data` |
data.frame |

`arrangeTerms` |
character vector of column expressions to arrange by. |

`...` |
not used, force later arguments to bind by name. |

`.by_group` |
logical, should data be sorted by grouping variables (if present). |

`strict` |
logical if TRUE accept only name and desc(name) terms. |
