Proofread and improve the whole class reference
- Document a few more properties and methods
- Add more information to many classes
- Fix lots of typos and gramar mistakes
- Use [code] tags for parameters consistently
- Use [b] and [i] tags consistently
- Put "Warning:" and "Note:" on their own line to be more visible,
  and make them always bold
- Tweak formatting in code examples to be more readable
- Use double quotes consistently
- Add more links to third-party technologies

Abstract base class for range-based controls.
</brief_description>
<description>
Range is a base class for [Control] nodes that change a floating-point [i]value[/i] between a [i]minimum[/i] and a [i]maximum[/i], using [i]step[/i] and [i]page[/i], for example a [ScrollBar].

<description>
Binds two ranges together along with any ranges previously grouped with either of them. When any of range's member variables change, it will share the new value with all other ranges in its group.

<method name="unshare">
<return type="void">
</return>
<description>
Stops range from sharing its member variables with any other.

<members>
<member name="allow_greater" type="bool" setter="set_allow_greater" getter="is_greater_allowed">
If [code]true[/code], [member value] may be greater than [member max_value]. Default value: [code]false[/code].
</member>
<member name="allow_lesser" type="bool" setter="set_allow_lesser" getter="is_lesser_allowed">
If [code]true[/code], [member value] may be less than [member min_value]. Default value: [code]false[/code].
</member>
<member name="exp_edit" type="bool" setter="set_exp_ratio" getter="is_ratio_exp">
If [code]true[/code], and [code]min_value[/code] is greater than 0, [code]value[/code] will be represented exponentially rather than linearly.
</member>
<member name="max_value" type="float" setter="set_max" getter="get_max">
Maximum value. Range is clamped if [code]value[/code] is greater than [code]max_value[/code]. Default value: [code]100[/code].
</member>
<member name="min_value" type="float" setter="set_min" getter="get_min">
Minimum value. Range is clamped if [code]value[/code] is less than [code]min_value[/code]. Default value: [code]0[/code].
</member>
<member name="page" type="float" setter="set_page" getter="get_page">
Page size. Used mainly for [ScrollBar]. ScrollBar's length is its size multiplied by [code]page[/code] over the difference between [code]min_value[/code] and [code]max_value[/code].
</member>
<member name="ratio" type="float" setter="set_as_ratio" getter="get_as_ratio">
The value mapped between 0 and 1.
</member>
<member name="rounded" type="bool" setter="set_use_rounded_values" getter="is_using_rounded_values">
If [code]true[/code], [code]value[/code] will always be rounded to the nearest integer. Default value: [code]false[/code].
</member>
<member name="step" type="float" setter="set_step" getter="get_step">
If greater than 0, [code]value[/code] will always be rounded to a multiple of [code]step[/code]. If [code]rounded[/code] is also [code]true[/code], [code]value[/code] will first be rounded to a multiple of [code]step[/code] then rounded to the nearest integer.
</member>
<member name="value" type="float" setter="set_value" getter="get_value">
Range's current value.
</member>

<signals>
<signal name="changed">
