A pair of filters `l₁`, `l₂` has `tendsto_Ixx_class Ixx` property if `Ixx a b` tends to `l₂.small_sets` as `a` and `b` tend to `l₁`. In all instances `Ixx` is one of `Icc`, `Ico`, `Ioc`, or `Ioo`. The instances provide the best `l₂` for a given `l₁`. In many cases `l₁ = l₂` but sometimes we can drop an endpoint from an...
